HYDRAULIC MOTOR.

SPECIFICATION forming part of Letters Patent No. 663,337, dated December 00- Application filed May 12, 1900. Serial No. 16,455. (No model.)

To ntZZ whom it rncby concern.-

Be it known that I, GEORGE F. GEMMILL, a citizen of the United States of America, and a resident of York, York county, State of Pennsylvania, have invented a new and Economical Hydraulic Motor, of which the following is a specification.

My invention relates to a novel hydraulic motor, consisting in the combination as hereinafter described,and more particularly pointed out in the claim.

In the drawings fully illustrating myinvention, Figure l is a perspective View showing the vital parts in a hollow shaft. As shown in this figure, there are fixed in the hollow shaft A two blade parts B, lying in portions of two planes oblique to shafts axis and to each other. It will be noticed that the extremities of blades B lie in the same transverse planes, that their inner edges lie in or near a longitudinal plane passing through axis of shaft, and that their outer edges are fixed to shaft. Broken lines F show position of longitudinal plane.

Fig. 2 shows the hollow shaft equipped with my blade arrangement mounted with pulley on bearings 3. If pressure be supplied to shaft through supply-pipe c, it can be seen how it, with pulley, is forced in arrow direction.

Now, having described my invention, what I claim is- In hydraulic motors, a combination which consists of hollow shaft and two blade parts lying in portions of two planes oblique t0 shafts axis and to each other, their extremities in the same transverse planes, their inner edges in or near a longitudinal plane passing through axis of shaft and outer edges fixed to shaft.

In testimony whereof I affix my signature in the presence of two witnesses.

GEORGE E. GEMMILL.
